AbstractIn recent material removal process, Conventional machining like drilling, milling, grinding etc can be replaced by Non traditional machining because of high surface finish, Minimum tool wear and excellent dimensional accuracy. Particularly for machining high hardened materials like ceramic, composites and super alloys Electrical discharge Machining (EDM) process is preferred. In this paper an attempt is made to machining of Aluminium nano composites. It is fabricated by melting Aluminium alloy 6061in a crucible and stirred the preheating Multiwall carbon nanotubes (MWCNT) with different Wt% using stir casting technique. Now 16 Experiments with varying three input parameters Current, Pulse On and Pulse Off having four level of factors were conducted. The output parameters can be measured by Surface Roughness value (SR), Material Removal rate (MRR) and Tool wear rate (TWR). From the Taguchi analysis, it is determined that MRR, TWR and SR gives good results when using copper electrode for machining of aluminum nano composite.
